Additional Specializations

Along with computational simulation, our team also provides engineering services in the areas of design, manufacturing processes, and failure analysis. Along with advanced polymer analysis, our company also uses in-house testing facilities for material testing purposes, noting factors such as shear, fatigue, and long-term creep. Through failure and root cause analysis, we help determine the causes of component and system failures by analyzing different failure scenarios.

Furthermore, Veryst Engineering offers engineering assistance in the development of medical devices. From CAD modeling to design for manufacturing and assembly, our team has helped design numerous devices, such as vascular stents, hip implants, catheters, and surgical instruments.

Featured COMSOL Multiphysics Projects

Here are some examples of our projects using COMSOL Multiphysics:

Peristaltic pump fluid-structure interaction.

Peristaltic pumps move fluid by squeezing an elastomeric tube, causing the fluid inside the tube to follow the motion of the roller. We developed a fluid-structure interaction model of the operation of a peristaltic pump. Capturing the deformation of the tube, rollers, and fluid, this model is useful for investigating the effects of pump design variables, such as tube occlusion, tube diameter, and roller speed on the flow rate and stress state in the tube.

Sea floor energy harvesting.

Our team developed proof of concept models for a device designed to harvest energy from constant low-speed ocean floor currents in order to power ocean sensors. In the design shown above, a bluff body is inserted in the flow path to generate Karman vortices, which are then directed to an energy conversion device.

Thermal analysis of a Calrod.

A Calrod is a heating element that converts electricity into heat through Joule heating. We developed a multiphysics model of a Calrod composed of a heating wire, surrounded by a magnesium oxide insulation and encased in a stainless steel tube. Heat transfer within a Calrod occurs through conduction and radiation.

Bergstrom-Boyce material model for elastomers.

The Bergstrom-Boyce material model is accurate for modeling the behavior of a wide range of elastomers and rubbers. The model accounts for the nonlinear rate-dependent deformation of elastomers as well as Mullins damage. We implemented the equations governing the viscoelastic deformation and Mullins damage using COMSOL software.
